hello,

i was trying to compile a renderman shader, for RFM 2.0 eval version, in a text editor - saved with a .sl extension.

for some weird reason when i go to the command prompt and try to compile it there i get  
the following error:

CODE  
ERROR: Cannot find preprocessor for shader file filename

can someone help me as to the nature of the problem and help me resolve it? it has been  
driving me nuts.

i have already set the proper environment variables.

any help will be much appreciated!

thanks!

cheers,  
SD
